When your flipping through the channels and you see an old man on Ghost Hunters saying, "Thats shpooky." And then when anything from something weird, funny, strange, scary happens you say, "Thats shpooky!"
Or, when your friend does something stupid or strange you call them shpooky.
PLUS, its fricken fun to say. Way better than normal old, "spooky"
"Leah i just saw an obese child and stole its food."
"Da fuck? Ally youre shpooky."
